Routine Exams by Age: What's Worth Considering

Why routine exams matter (and why so many of us put them off)

Have you ever caught yourself thinking “I feel fine, so I don’t need to see a doctor right now”? This reasoning is very common — and completely understandable. A busy life, exam costs, fear of discovering something serious, and even the sense that check-ups are “for sick people” make many of us delay preventive care. The problem is that some serious conditions — like hypertension, type 2 diabetes, and certain cancers — can develop for years without causing noticeable symptoms.

That’s exactly where routine exams come in. They aren’t signs of weakness or excessive caution: they’re tools that help doctors and patients identify changes early, when the chances of effective management are usually higher. According to the World Health Organization (WHO), early detection is one of the fundamental pillars of healthcare, especially for chronic non-communicable diseases.

This article brings together general information about exams and evaluations typically considered at each life stage, based on recommendations from bodies like the Brazilian Ministry of Health and Brazilian medical societies. It does not replace a medical consultation — each person has a unique history, risk factors, and needs. Use this content as a starting point to talk with your healthcare professional.

What is prevention and why it changes with age

Talking about routine exams means talking about two main types of prevention:

Primary prevention: preventing a disease from appearing (vaccination, healthy habits, risk factor control).
Secondary prevention: detecting a disease in its early stage, before it causes major damage (screening and periodic exams).

Routine exams fit mainly into secondary prevention. But here’s an important point: not every exam makes sense for every age. Screening has value when the disease in question is prevalent in that group, when a reliable test exists to identify it, and when early diagnosis changes the prognosis. That’s why recommendations vary — and why personalized medical guidance is irreplaceable.

Childhood and adolescence: building the foundation

In the first decades of life, medical follow-up is frequent almost by definition — vaccines, pediatric consultations, developmental evaluations. Still, there are some points that deserve special attention.

Frequent evaluations in childhood (0–12 years)

Neonatal screening (Heel Prick Test): performed shortly after birth, it screens for metabolic, genetic, and infectious diseases that can be managed early. In Brazil, the National Neonatal Screening Program has expanded in recent years.
Eye Test and Hearing Test: also done shortly after birth, they evaluate vision and hearing.
Growth and development monitoring: done at childcare consultations, assesses weight, height, developmental milestones, and oral health.
Complete blood count and parasitic testing: may be requested based on history and region.
Blood pressure: from age 3 onwards, can be checked during routine visits.

Adolescence (13–19 years)

In addition to keeping vaccines up to date (the National Immunization Program calendar covers this age group), adolescence is a period when issues related to mental health in adolescence, reproductive health, and habits that will impact adult life arise. Basic exams like complete blood count, glucose, and lipid profile may be requested depending on family history. Sexually active adolescent girls should talk with a gynecologist about STI screening and reproductive health.

Young adults (20–39 years): don’t underestimate this phase

There’s a cultural idea that healthy young adults don’t need medical follow-up. But it’s precisely in this phase that many habits solidify — and conditions like hypertension, dyslipidemia, and type 2 diabetes can begin silently.

Evaluations typically considered:

Blood pressure: should be checked regularly. The Brazilian Society of Cardiology recommends periodic checks even without symptoms.
Fasting glucose: especially important for those with a family history of diabetes, excess weight, or other risk factors.
Lipid profile (cholesterol and triglycerides): may be requested from age 20 onwards for those with a family history of cardiovascular disease.
BMI and abdominal circumference: evaluated by the doctor as part of the clinical exam.
Oral health: regular dental visits help prevent cavities, gum disease, and in rarer cases, identify lesions early.
Vision health: especially for those who wear glasses or contacts, or have a family history of glaucoma.
For women: the Pap smear (cervical cytology) is recommended by the Ministry of Health from age 25 onwards to screen for cervical cancer. Breast exams also enter the conversation with the gynecologist.
For everyone: vaccination up to date (hepatitis B, dT, yellow fever based on region, annual influenza, and recently introduced vaccines like HPV, which in the public calendar has reached broader age groups).

Middle-aged adults (40–59 years): the period of greatest vigilance

From age 40 onwards, the risk for various chronic diseases increases significantly. This is generally the period when doctors tend to expand the range of evaluations.

Frequently considered evaluations:

Glucose and glycated hemoglobin: diabetes screening becomes more systematic.
Complete lipid profile: assessment of overall cardiovascular risk.
Electrocardiogram (ECG): may be requested as a baseline, especially for those engaging in intense physical activity or with cardiac risk factors.
Colorectal cancer screening: from age 45 or 50 onwards (the exact range varies by guidelines and family history), tests such as fecal occult blood or colonoscopy may be indicated.
Mammography: for women, the Ministry of Health recommends mammography every two years between ages 50 and 69, but women with relevant family history may be screened earlier — which reinforces the importance of talking with your doctor.
Bone density scan: especially for women in perimenopause, assesses osteoporosis risk.
Thyroid function (TSH): may be evaluated, especially in women, as thyroid problems are more common in this group.
For men: exams related to prostate health (PSA and digital rectal exam) come up in conversation with the urologist, usually from age 50 onwards — or earlier if there’s family history.
Mental health: accumulated stress, hormonal changes, and midlife pressures can significantly affect emotional well-being. Don’t hesitate to include this dimension in consultations.

Older adults (60 years and older): expanded and personalized care

In this phase, medical follow-up tends to be more frequent and encompasses dimensions beyond laboratory exams: mobility, cognition, eye and hearing health, and fall risk assessment are part of comprehensive elderly care.

Frequently evaluated points:

Comprehensive geriatric assessment: many specialists recommend a periodic global evaluation that considers not just diseases, but functionality, cognition, mood, and social support network.
Chronic disease management: for those already diagnosed with hypertension, diabetes, or dyslipidemia, regular follow-up is even more essential.
Eye and hearing health: glaucoma, cataracts, and hearing loss are more frequent and deserve specialized evaluation.
Bone density scan: recommended for women from age 65 onwards and for men from age 70, or earlier in cases of elevated risk.
Vaccination: the elderly calendar includes important vaccines such as annual influenza, pneumococcal, herpes zoster, and dT boosters.
Cognitive evaluation: simple tests applied by the doctor can help identify early memory changes.
Mental health and social isolation: loneliness and depression are underdiagnosed in older adults. Maintaining social connections and pleasurable activities typically contributes to well-being — and seeking professional support when necessary is always valid.

A practical guide to organizing your preventive care

Record your family history. Heart disease, diabetes, cancer, and other conditions in parents and siblings are valuable information for the doctor to assess your individual risk.
Bring a list of questions to your appointment. Write down what you want to ask so you don’t forget during the visit.
Keep your exam results. Maintaining a file — physical or digital — of your results over the years helps identify trends.
Check your vaccination record. Adults often discover that important vaccines are overdue.
Don’t ignore symptoms due to “lack of time”. Persistent fatigue, pain, mood changes, or any change that catches your attention deserve to be reported to your doctor.
Ask about frequency. Not every exam needs to be done every year. The doctor can guide the appropriate frequency for your case.

When to see a healthcare professional

In addition to regular preventive consultations, some signs call for more immediate attention. See a doctor if you notice:

Chest pain, shortness of breath, or palpitations
Sudden changes in vision
Unintentional weight loss
Unusual bleeding anywhere in the body
Symptoms that persist for more than two weeks without improvement
Significant changes in mood, sleep, or cognition

If you’re experiencing intense emotional suffering or in crisis, know that help exists. In Brazil, the CVV (Center for the Valuation of Life) serves free of charge at the number 188, 24 hours a day, every day. In physical or mental emergencies, the nearest health service or SAMU (192) are the way to go.

Taking care of yourself is a continuous act

Routine exams aren’t isolated events — they’re part of a continuous relationship with your own health. More than a list of procedures, they represent the opportunity to know your own body, identify what works well and what can be adjusted, and build a history that guides decisions throughout your entire life.

There’s no wrong age to start taking care of yourself with more attention. If you don’t yet have a healthcare provider, finding a general practitioner or family doctor is a good first step. The SUS offers this entry point through Primary Healthcare, and many Brazilian municipalities have Basic Health Units that provide consultations and preventive exams for free.

Taking care of yourself doesn’t need to be perfect — it just needs to be consistent.
